Laminar gravity controlled film condensation of multicmponent mixtures on a vertical flat plate is theoretically treated in the same manner as that for forced convection condensation. The governing equations of heat and mass transfer for multicomponent mixtures, which are coupled complicatedly with respect to the buoyancy term as well as to the other concentration terms, are reduced to those for binary mixtures by orthogonal transformation expect for the vapor momentum equation. Then, generalized simultaneous algebraic equations for predicting the heat and mass tranfer characteristics of condensation of multicomponent mixtures are derived on the assumption that the treatment of buoyancy force for single-phase free convection of binary and ternary mixtures with simultaneous heat and mass transfer can be extended to the condensation of multicomponent mixtures of higher order.
